SHEAR THINNING ETHYLENE/α-OLEFIN INTERPOLYMER AND ITS PREPARATION

PROBLEM TO BE SOLVED: To provide a polymer having large viscosity change by shearing without using an expensive monomer such as norbornadiene.SOLUTION: Interpolymers contain ethylene, at least one α-olefin monomer, and at least one diene monomer, and have a Processing Rheology Ratio (PRR) of at leas...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polymer having large viscosity change by shearing without using an expensive monomer such as norbornadiene.SOLUTION: Interpolymers contain ethylene, at least one α-olefin monomer, and at least one diene monomer, and have a Processing Rheology Ratio (PRR) of at least 10 {PRR=(interpolymer viscosity measured at a shear rate of 0.1 rad/sec and at 190°C)/(interpolymer viscosity measured at a shear rate of 100 rad/sec and at 190°C)+[3.82-interpolymer Mooney Viscosity (ML1+4 at 125°C)]×0.3}, a molecular weight distribution (Mw/Mn) of at least 2.2, and a Mooney Viscosity (ML1+4 at 125°C) of at least 15.
